Overview
Affected versions of this package are vulnerable to Use After Free in the BIO_new_NDEF() function. A new filter BIO can be freed, with the function returning a NULL result indicating a failure. But the BIO passed by the caller still holds pointers to the previously freed filter BIO. This could allow an attacker to cause a crash.
